PROCESS F MAKING OPEN-WORK ORNAMENTAL PANELS.

SPECIFICATION forming part of Letters Patent No. 351,060, dated October 19, 1886.

Application filed August 25, 1885. Serial No. 175,255. (No model.)

To aZZ whom it may concern.-

Be it known that I, FREDERICK BIANKEY, of IVilliamsport, Lycoming county, Pennsylvania, have invented a certain new and useful Improvement in Processes of Making Open Vork Ornamental Panels, of which the following is a specification.

My invention consists in a new method of producing open-work or reticulated panels from wood or other suitable material, the process being simpler and cheaper than any now n use.

In the accompanying drawings, Figure 1 is a plan View of a boardwhich has been sub jected to the first steps of my process. Fig. 2 represents an edge View of said board, and also a side view of a strip cut therefrom in the second step of said process. Fig. 3 is a top view of said strip. Figs. 4 and 5 represent, re spectively, side and top views of said strip after it has been subjected to a third step, which I consider desirable, though not essen tial, in said process 5 and Fig. (i represents the openwork or reticulated panel finally formed, Fig. '7 being a section thereof on the line 00 00 of Fig. 6.

I carry my new process into effect in the following manner: A suitable piece of timber be ing selected, I subject it to the action of a rotary cutter or series of cutters, whereby the surface of the material is cut transversely to the grain in channels and ridges. Thus, to form the particular design represented in the drawings the wood is cut transversely with channels A and intermediate ridges, B, having convex sides, as shown in Fig. 1. The plank or board, having been cut in this way on both sides, is afterward divided longitudinally with the grain or in a direction at right angles to said channels, as indicated by dotted lines, Fig. 1, thus producing a number of strips, G, similar to those shown in Figs. 2 and 3, the tops of the ridges now appearing as projections 1) upon each side of a fiat strip, and the sides of the channels A now appearing as curved V shaped depressions a between said projections. To produce a highly-ornamental surface in the finished panel, I then prefer to pass the strips shown in Figs. 2 and 3 through a molding-machine, forexample, whereby they are beveled along both edges and indented or transversely channeled, as shown in Figs. 4 and 5 at D and B, respectively. The strips are then placed side by side, and the ends of the several projections B are glued or otherwise securcd together. The open-work panel thus produced is shown in Fig. (3, the curved V- shaped indentations a eorrcspondin g to form the openings.

I do not claim herein the process of making ornamental surfaces by first cross-cutting the wood, then splitting the same, and finally securing the strips together so as to reform the surface; nor do I claim the method of ornamenting wood by a design produced by crosscutting; nor the particular design here shown by an ornamental open-work panel. All these inventions are the subject-matter of separate applications filed or to be filed by me.

I do not limit my claim to the combination of all the steps above mentioned, since, for instance, the third step may be omit-ted, and the strips shown in Figs. 2 and 3 may be formed into a panel by uniting their edges without further ornamentation, the result in such case being an open-work panel having a flat or plane surface. The panel thus formed may then be ornamented in any desired manner as, for instance, by cutting beveled channels 0, Fig. '7, longitudinally with the grain and along the lines of junction of the strips and by cutting similar channels, F, transversely across the surface. I do not, therefore, limit the invention to the application of any particular amount of ornament to the panel formed by my process.

I claim as my invention- 1. The hereinbefore-described process of making ornamental open-work panels, which consists in, first, producing upon the material a series of alternating channels and ridges transverse to the grain; second, dividing said material into strips at right angles to the direction of said channels; and, third, securing the said strips together with their channeled and ridged edges in juxtaposition, substantially as described.

2. The hereinbcfore-described process of making ornamental open-work panels, which and, fourth, securing said strips together with consists in, first, producing upon the material their channeled and ridged edges in juxtapoa series of alternating channels and ridges sition, substantially as described.
